Background:Chondrosarcoma is an unsual tumour involving the skull base. This malignant tumour most commonly occurs in young adults, and it is found in countless anatomic locations, including long bones, flat bones, and craniofacial bones. It is necessary to distinguish myxoid chondrosarcoma from the chondroid variant of chordoma, as the treatment protocol and prognosis varies for both conditions.
Case report: A 30-year-old female came to our hospital with a complaint of right nasal obstruction for the past few months. The patient underwent a Computed Tomography(CT) scan of paranasal sinuses including base of skull was ordered. The CT scan revealed a well-defined lobulated hypodense soft tissue density mass lesion centered in the body of the sphenoid bone. The mass had internal ring and arc type of calcification. The mass was filling the sphenoid sinus, whole right sided ethmoidal sinuses, and eroding the skull base to reach into the extra-dural space. Mass was extending into medial part of right orbit causing compression of the medial rectus muscle and resulting in lateral side proptosis. Post obstructive sinusitis changes were observed in right frontal and maxillary sinuses. The patient underwent surgical management.
Conclusion: Sphenoidal chondrosarcoma is a rare entity; misdiagnosing it or missing the findings may have profound implications for the patient. CT provides an accurate and detailed depiction of the entity.
